Protherm gas boilers: product lineup, installation and usage tips

To date, the most budget and common type of fuel is natural gas, and this is despite the fact that its cost is growing. It is these qualities that make it possible to apply it so widely in heating systems, mostly in private cottages, summer cottages or where there is no centralized network.

This article discusses the model of gas boilers by Protherm, their advantages and disadvantages, as well as feedback from the owners.

Protherm is a Czech manufacturer that is very popular in the Russian market for heating devices. The company is engaged in the production of gas boilers that meet modern requirements and have excellent operating and technical characteristics.Protherm products are worthy competitors to Asian and European counterparts, they meet the most biased requirements. That is what makes them so popular.

Each Protherm model has one feature — it is built by one employee., that is, one specific person is responsible for each boiler. The model line of the company includes floor and wall boilers, as well as boilers and cascade modular structures.

Protherm fights for the quality of its products, observing the following requirements and metrics:

• Seven production lines: three of them contain floor models, three - wall-mounted boilers, the latter includes structures operating at high power.
• Mandatory output control of each product in each of the lines.
• More than two hundred different types of components manufactured by European firms are involved in production.
• With the help of the SAP information system, the production process is managed, as well as the development of short and long-term development plans for the company
• All equipment used in the work is tested in leading laboratories every year. In addition, a system of quality management is checked at a similar frequency.
• In addition to the output control, every day two percent of the boilers released are tested in detail, and each of the boilers is checked by the control unit and security system elements.
• The company is constantly upgrading and improving its technological base.

One of the undoubted advantages of Protherm gas boilers is their environmental friendliness and ease of operation. They can be installed in medical institutions, schools, kindergartens.

Of the other advantages of the models can be noted:

• Multifunctional. Due to the presence of two circuits (one for heating, the other for hot water), the boiler can be used to heat both country houses and non-residential buildings.
• Efficient operation due to the presence of two independent heat exchangers.
• Reliability and long service life.
• Relative budget: price "plug" on the model line Protherm - from 27 to 50 thousand rubles.
• Availability of purchase. Products are presented quite widelyAny specialty store has a Protherm model in stock. If you need to replace individual components, they can be ordered from the authorized dealer of the brand.
• Each product is automated. If a malfunction occurs, this is immediately reflected on the sensors; during normal operation, this is also clearly visible.
• Low fuel consumption. There are also winter-summer mode switches.
• Minimalistic design.

All gas boilers are divided into two large groups (at the place of their mounting and installation) - wall and floor. The latter are more powerful, they are mounted on the floor or on a platform equipped for this purpose. But since this type of boiler takes up a lot of space and is quite cumbersome, wall-mounted appliances are more popular in private homes. As a rule, they are quite enough to warm a one or two-story building. Wall constructions, as their name implies, are mounted directly on the wall.

In addition to the above classification, gas boilers are divided into single and double circuit. For the first you need to install an additional boiler. At the same time, they consume hot water to the maximum and are not burdened with excessive load.

However, it should be noted that among the model lines Protherm single-circuit version is rare. Basically, dual-use products. This means that in one circuit so-called “technical” water is heated, which cannot be drunk, but which can be washed and heated. And the second circuit heats the drinking water, it goes directly to the tap in the kitchen. This is certainly much more convenient, because there is no need to filter the water for drinking or to buy it.

According to what type of combustion chamber is installed in the product, they are divided into models with an open chamber or with a closed one. The first type is differently called “chimney”, as it requires the equipment of the chimney. Atmospheric burners are installed in the boilers with an open combustion chamber.

Also, gas boilers are both volatile and those that do not depend on whether there is a network or not, that is, are non-volatile.

The general classification of boilers is to divide them into:

• atmospheric;
• condensation;
• fan.

The colder the exhaust gases, the more economical the boiler will be. The palm is held by condensing boilers, since the temperature of the combustion products fluctuates around the 300 C mark. At the fan boilers, this temperature is higher - about 55 degrees, and atmospheric - 110.

Thus, we can conclude that it is the condensing boiler that will pay off the fastest. However, they are not the most durable, and atmospheric models. However, both experts and users are unanimous - this is practically their only advantage. Their efficiency is low, they only require installation in a well-ventilated room, where there is a window, the products of their combustion can get inside the room and pollute the air in it. Atmospheric models for the most part are mounted on the floor.

Inside the fan boilers there are moving parts, and this reduces their reliability. However, they have the advantages leveling this minus.They are safer due to hermetic fire. Exhaust gas will not enter the air. Specially mounted pipe for its withdrawal is not needed, rather horizontal, mounted in the wall. Through it air from the street will be taken.

Condensing boiler has the same properties as the fan.while it is much more economical. The price is the biggest drawback of such a model, because it is high. Condensate remains in the water drainage system, icicles are not formed. Plus - the gas consumption is much less, which saves money on fuel.

Every consumer who wants to install a gas heating device at home (or in another building or structure) makes a choice based on his requirements, financial possibilities and, of course, the characteristics of the room that he plans to heat.

As for the model range (and as we remember, there are seven lines of Protherm), then in this section we will focus on the most popular consumer types.

First of all, it is “Jaguar” - the champion among the acquired wall structures. This view is ideal for buildings with an area not exceeding 220 m2, that is, for villas, country cottages.Jaguar not only heats, but also provides hot water. It has two separate heat exchangers. Fuel for it is the main gas, its consumption is relatively small - from 2.73 m3 / hour.

One of its heat exchanger is made of copper, the other is made of stainless steel. Included with it is a circulation pump. Users rate this model extremely positively because of the convenience and ease of installation and operation.

No less popular "Panther" - another wall model. The strength of its hydraulic unit is enhanced by the composite materials from which it is made. The design of the product has a pump and tank, as well as a special option "Comfort". Thanks to her, the water heats up in just 5 seconds. "Panther" is powerful enough - the range ranges from 12 to 35 kW.

"Cheetah" - a double-boiler, has two capacities: 11 and 23 kW. This model does not require the presence of a chimney, the products of combustion go through the coaxial system.

Another option from the model range - "Lynx". She also has two separate heat exchangers with the ability to separately adjust the temperature level in each.Since this model is two-circuit, it has a circulating pump and an expansion tank, the volume of which is 7 liters. "Lynx" is available in two power options - 24 and 28 kW.

The most controversial reviews from consumers are received on the Leopard model. This product also applies to the wall ruler. To adjust the "Leopard" has one automatic window.

Users note that at an outdoor temperature of -30 and below the boiler heats the room slightly. In addition, at low street temperatures, the product overheats, and during long frosts below 40 degrees, the heat sensor often fails and must be replaced.

The “Bear” is a popular model among floor standing models - a single-circuit device with a capacity of up to 44% kW. Medved operates on two types of fuel - both main gas and liquefied gas are suitable for it. The model is non-volatile, works without connection to the electrical network. "Bear" is usually used for heating industrial premises.

The Grizzly model is more powerful and at the same time simple. It can be used to heat large rooms of up to 15 thousand m2.“Grizzly” is the most eco-friendly version of the floor-standing boiler, but its disadvantage is that it depends on the power grid and does not work without it.

"Wolf" - floor non-volatile modelequipped with a steel heat exchanger. Even during unstable power supply, it provides uninterrupted heating of the room. Designed for heating only, has one circuit.

"Beaver" - boiler with cast iron heat exchanger, works on solid fuel: coal or wood. Also non-volatile. Develops power up to 45 kW. It is possible to replace the sections and complete them, based on the needs of the consumer.

To connect the boiler to the electrical network of a private house, it is necessary to intervene in its internal structure. This type of work is carried out only by Protherm certified personnel.

If you decide to do it yourself, you need to remember that after that, most likely, you will not be able to service the boiler and eliminate interruptions in its work under warranty.

The degree of warmth and comfort in the house depends on how high-quality materials are selected and how skillfully the installation is carried out.If you choose the correct boiler strapping scheme, the system will be protected from overheating, overload, and all the rooms in the house will be heated evenly. Arranging the strapping scheme, you need to be guided by the building regulatory documentation.

Strapping is the whole heating system minus batteries (radiators). The system includes a large number of nodes and devices, but even the amateur can install the simplest strapping scheme.

Binding serves to perform a number of functions, such as:

• Monitoring the pressure in the system. With proper installation, the pressure remains at about the same level, without increasing or decreasing.
• Removal of excess air. Due to air bubbles, traffic jams are formed, which leads to incomplete heating of radiators. The resources are still consumed, and heating is not as efficient. Properly performed strapping helps prevent this.
• Reduction and prevention of blockages in the heating system. If there are errors in the strapping inside the radiators and pipes, dross forms and contaminates the system.Fuel is consumed in excess, and the quality of heating decreases.
• Connecting other circuits. If desired or necessary, you can attach to the strapping storage boiler, floor heating.

The boiler is set up on the LCD display, and adjustment is also performed there.

Before starting installation works of the room regulator, the boiler is disconnected from electricity - this is a prerequisite. Each boiler has a tubular fuse, it can be seen on the control panel. If the regulator has a relay switch, then the maximum load on it should not exceed 24 watts. The regulator is connected to the boiler using a two-wire cable. Copper wire having a cross section of 1.5 mm2 is best suited for this.

The factory assembly involves installing a jumper in the place where the room controller should be connected. Before you begin the process of connecting the regulator, this jumper is removed. In other cases, it does not need to be removed.

The manufacturer recommends installing only “native” regulators on the Protherm boilers, that is, Protherm Thermolink B or P.

The wires from the regulator (room) are connected to the terminal board of the boiler.In the case of installation of regulators recommended by the manufacturer, the function of equithermal regulation is available. In this method of device control, the temperature of the coolant is adjusted depending on what the outside air temperature is. A sensor is installed on the boiler that monitors the fluctuations in the outside temperature, and the regulator changes the temperature of the water in the heater (and, eventually, indoors), allowing you to create a comfortable atmosphere in the house.

Included with each Protherm gas boiler is instructions for its proper operation.

As a rule, all the boilers of the company are easy to use, each display is lit, reflecting the main indicators: temperature, the presence of errors.

The most common problems are listed in the instructions, as well as how to solve them. If you cannot fix the error yourself, you should contact the store where the boiler was purchased.Some problems are fixed under warranty. If necessary, serious repairs can be offered to replace the unit with a similar one.

Basically, people who bought models of Protherm boilers, note their cost-effectiveness (low fuel consumption), high-quality assembly, reasonable price and long service life without failures. In addition, many are satisfied that the boiler heats the air in a large area.

Of the disadvantages of the owners indicate a significant weight of floor structures, as well as the relatively high cost of products.
